Antimony acid

Antimony acid is an inorganic compound of antimony oxide and water. Antimony acid exists in solution in several forms, for example, hexahydroximony H [Sb (OH) ₆ ]. Upon precipitation, a gel with a variable water content is obtained; with prolonged drying, insoluble metasimic acid HSbO _{3 is} obtained. Salts of antimony acid are called antimonates (antimoniates) or oxystibates .

Getting

Nitric acid oxidation:

{\mathsf {3Sb+5HNO_{3}\ {\xrightarrow {\ }}3HSbO_{3}+5NO\uparrow +H_{2}O}}

{\ displaystyle {\ mathsf {3Sb + 5HNO_ {3} \ {\ xrightarrow {\}} 3HSbO_ {3} + 5NO \ uparrow + H_ {2} O}}}

By the interaction of its salts with acids:

{\mathsf {K[Sb(OH)_{6}]+HCl\ {\xrightarrow {\ }}H[Sb(OH)_{6}]+KCl}}

{\ displaystyle {\ mathsf {K [Sb (OH) _ {6}] + HCl \ {\ xrightarrow {\}} H [Sb (OH) _ {6}] + KCl}}}

Chemical Properties

Reacts with alkalis:

{\mathsf {H[Sb(OH)_{6}]+NaOH\rightarrow Na[Sb(OH)_{6}]+H_{2}O}}

{\ displaystyle {\ mathsf {H [Sb (OH) _ {6}] + NaOH \ rightarrow Na [Sb (OH) _ {6}] + H_ {2} O}}}

Derivatives
